PIPE-COUPLING FOR RAILWAY-CARS SPECIFICATION forming' part of Letters Patent No. 396,908, dated January 29, 1889.

Application filed December 15, 1887. Serial No. 257,968. (No model.)

T0 aZZ whom, it may concern:

Be it known that l, 'PHILLIP s. WisEiiiAN, a citizen of the lnited States, residing' at bpri n field, in the county of Clark and State of Ohio, have inventedv eertain new and useful lmprovements in I'Ieatingl Appliances for Railway-(lars, oit which the tollmving is a speeitication, referenee being' had therein to the aeeompanying drawin This invention 'relates to eertain new and useful improvements in heating' appliances tor steam-railway ears; and the i n ventiou consists ot' the peculiarities hereinafter appearing, and more fully pointed out inthe claims.

ln the aeeoinpanying drawings, forming a part ot' this speeiiieation, and on which like re teren eeeletters in dieate corresponding' parts, llig'nre ,l represents a side elevation ot' two service-pipes, the Coupling therefor, and a distributing-pipe, showin the ad ,jacent ends of two ears in section; Fig'. il, a longitudinal seetional view ot a portion ot1 two serviee-pipes, with the,eoupliiu,r partly in section and partly in elevation; Fig'. il, a pla-n view ot' a car-idoor, with the sides in seetion, showing' the arrangement ot my service and distributing pipes, and showing' also the mljaeinit ends ot' two ser\\'ieeepipes and their coupling', l `ig'.+1^,a vertical sectional view on the line a: otf Fig. 3; Fig. 5, a similar view to Fig'. il with ehangein .the servici-.'-pipe; Fie'. t1, a seetional view on the line g/ ,1/ ot File'. 5, Fig'. 7, a detail view of the service-pipe and eoupiine'pipe; Figi'. tl, a detail view ot' a eoupliugpipe and a clamp.

The letters A and lj designate the ai'ljaeent ends ot' two railway-ears ot' the ordinary c0nstruction. To theboiiom ot' eaeh, and preferably to the under side, are attached servieepipes (T and l). 'lhesepipes extend tromend to end ot' the ears,and are provided with entoffs E, for the purpose ot eontrollng the passage oli' the heating,` element in eonneetion Awith which theyare used. There are various arrangements which may be adopted 't'or the heat-distributing pipes 5 butl pret'in' substantially the arrangement shown, which consists ot.' the pipes F, which eonneet with the respective service-pipes and extend alone` the iioor ot' the ear, near the sides and ends thereof, and below the Flooring at the middle portion ot' the ends, so as lnot to obstruct the pipe may be conducted to all the distrilnit` ing-pipes, it" desired, while the same may be eut olif by one ot' the eoeks Il. lt is eontemplated to use generally only one ol' the serviee-pipes of a ear at a time; but two are pro vided on eaeh ear, so as to avoid one servieepipebeing on one side of' one ear and the other service-pipe on the other side of the other ear, in ease they should happen to be so turned with respeet to each other. Eaeh distrilniting-pipe F has conneetedto .itasuitable number ot' sub-distribnting pipes, l, whieh may oeeupy the space under each seat, it' desired. t

The letters J and .l designate theeoupling'- pipes, eaeh eonsistiirgr ot short seetii'ms havin a packing' at l, which snug-ly fits the servicepipes, respectively. Each serviee-pipe also has a head at L, which snugly ti ts the pipes .l and J, respeetively. A spiral spring' is se eured to the head L and the 'poriions K oi' eaeh pipe, the iiontraeting;A torce ol? wllieh tends to project the pipes .l and J toward eaeh other. Eat-h ot these pipes is provided at its outer entrance with ahead, M and N, respectively, substantially lienlispherieal in shape and hollow, so as to reeeive each a sphere, O, and torni a tight joint between them. The spheres O are also hollow, and are eon n ected by an .i ntervtai i ne' tubular neek, l". Each sphere is mmstructed with an enlarged opening', Q, which communicates with the pipes .l and J", resl'ieetivellv, i he lat ter vominunicatingr with the interior ot the pipes (l and l). This construction admits ot a universal movement between the heads M and N' and the respeeti ve spheres O,whereby the joint is aeeomminlated to the various Vinequalities and movements oil the respective ears. The spheres are held, or tu rther held, in the heads by means of clamps lionsisting et" two prongs, each ot' which emln'aees a sphere O, and een* nected with the heads M and N, as by a lng', S, extending; therefrom and bent down firmly IOO over the connected ends ot' the clamps in such a manner as to hold them. firmly against the spheres. I prefer to make the clamps of steel wire and coil the ends of each branch thereof, so as to form a convenient place to take hold of with the hand when itis desired to uncouple or couple the heads with the spheres, As shown in Fig. 2, it will be seen that the clamps are placed upon the opposite sides ol' the heads. This, however,is immaterial, and each head may carry one or more clamps. The openings Q are sufficiently large to prevent cutting ott the passage when the spheres are Oscillated to one side or the other and up or down. ready intimated, is that ot forcing' the heads M and N against the spheres, and also of allowing longitudinal yield when the cars approach and recede from cach other.

So far in this description I have kept the arrangement ot service-pipes shown in l, 2, 3, and 4 distinct from the arrangementshown in Figs. 5 and t3. )referring to the latter arrangement, (1 and D designate the service-pipes, which are placed under the The action ot' the springs T, as alplatt'orm and end o't' each car at about the j ment the cnt-otls E are not necessary, as the cut-offs H maybe mani pulatcd to prevent the escape of the heating element and to control its admission. This form is also cheaper than the other, and is therefore preferred. Again,

when the pipes are placed at the center inl stead of at the sides of the "ar, there is less movement between the spheres and the hemispherical heads. The sliding sections ot' pipe, with their hemispherical hea ds, are titted to the central servico-'pipes in the same manner as to the side service-pipes.

I contemlJlate using the invention to conduct steam from one car to the other, which .is to be received from some suitable source, preterablyt'rom the locomoiive-lmiler. ,Ilot air, however, maybe conveyed trom car lo car by .means ot' these inrmm'einents. l design to supply each end ot' each service-pipe with two extra spheres, the same to be attached to the car-lmdy, as suggested in Fig.

car are in use those of the other ear remain suspended by chains. I have already stated that one or both of the service-pipes of the car may be used at a time. This will be governed according' to individual circumstances. The eut-otl's E in the service-pipes prevent the steam or hot air from escaping to the rear ot' the last ear, and maybe manipulated to prevent the escape ot' the steam when changing a car from one train to another.

I-Iaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isM

l. The combination, with a car, of a heating service-pipe, a short section ot' pipe fitted within the same, and a spring connected to the service-pipe and to said section of pipe, and tending to project the latter from the A tormer, the said section of pipe having a hemispherical hollow head, two hollow spheres connected by an intervening neck, one of which lits said head and each of which has an opening opposite the intervening neck, and a spring-clamp secured to t-he head and embracing t-he sphere within it.

The combination, with a central servicepipe and a tubular section slidingly litted within it and provided with a hollow hemispherical head, a packing between the service-pipe and said tubular section, and a spiral spring connected with the servicepipe and section, and tending to project the latter Afrom the former, ot two hollow spheres connected together by an intervening hollow i neck and having openings opposite the ends of said neck, and a spring-clamp connected to each head and composed of two prongs which engage the respective spheres.

23. The combination, with a tubular section having a hollow approximately hemispherical head, and a spring-clamp secured to the head and divided into two prongs, of two hollow i spheres connected together by an intervening portion ot' the coupling.

YlYhile those of one hollow neck and each having' an opening in the end opposite the said neck, one of which is fitted into said head and is held by said clamp.

In Vtestimony whereot' l aftix my sign alture in presence ot two witnesses.
